The MK Diamond MK-700W 24-inch blade is a wet cutting asphalt blade for walk-behind flat saws, the size a paving or utility crew puts on when the cut has to reach full pavement depth. Part number 137414 is the 24-inch diameter with a .185-inch kerf on a 1-inch arbor, carrying a 12 mm segment height, and MK rates it for saws in the 8 to 20 horsepower range.
Asphalt is a soft, highly abrasive material, and that combination is exactly backwards from concrete: the aggregate scours diamond out of the bond far faster than a concrete cut does, so an asphalt blade needs a hard bond that holds diamond in place. Running a concrete blade in asphalt is the classic way to destroy a blade in an afternoon. The MK-700W is MK's standard grade blade for this material, and water does double duty here, cooling the segments and flushing an unusually heavy slurry out of the cut.
Use Cases
- Full-depth pavement cuts for utility trenching and service laterals
- Road repair and patch layouts where a clean vertical edge is required
- Parking lot and driveway removal cut to a straight line before breakout
- Municipal and DOT crews running walk-behind flat saws in the 8 to 20 hp range
- Green asphalt and overlay work where a dry blade would load up immediately
Matching the blade to the saw
MK publishes an 8 to 20 horsepower range for this blade, and that number matters in both directions. Too little power and the saw bogs, the blade dwells in the cut and heat builds. Too much and a standard grade blade is being asked to do production work that a heavier grade is built for. Confirm your saw is rated for a 24-inch blade, takes a 1-inch arbor and has a working water feed before ordering.

Frequently asked questions
Can I use this blade in concrete?
It is bonded for asphalt. Asphalt is soft and highly abrasive, so an asphalt blade uses a hard bond to hold diamond against that scouring. In cured concrete that same hard bond tends to glaze and stop cutting. Use a blade bonded for concrete on concrete, and keep this one for asphalt.
Does it have to run with water?
Yes. The MK-700W is a wet cutting blade. Water cools the segments and, just as importantly in asphalt, flushes a heavy slurry out of the cut so the blade is not grinding through its own debris. Make sure water reaches both sides of the blade before the cut starts.
What saw does a 24-inch blade go on?
A walk-behind flat saw rated for a 24-inch blade, with a 1-inch arbor and a water supply. MK rates this blade for the 8 to 20 horsepower range, which covers most mid-size self-propelled and push flat saws used for pavement work.
Why did my last asphalt blade wear out so quickly?
Undercutting of the steel core is the usual culprit in asphalt. The abrasive slurry erodes the core just below the segments until they lose support. Keeping water volume high enough to flush the cut, and not forcing the feed, are the two things most under an operator's control.
